Application inea March 5,1904. serial No. 196.736. v(No model.) Y

To a/ZZ whom it maylconoerrm. l t y Be iti known that I, JOHN L. MoHUN, a citizen 'of the United States of America, anda v .resident offTr'enton, county ofMercer, State Y 5 ofNew Jersey, have invented-'certain new and useful Improvements in-J ournal-Box Lids, of whichth'e following is vajspecication'.`v

My invention y'relatr-s to-jcertainnew and useful improvements in journal-box lids; and

1o the object o. my invention is `toprovide a' lid p ofthe ordinaryconstructionvnow in common vuse withrneans which will render the joint between the g lid and. its seat` on the journal-box dust-tight. '.f In journal-boxes vand lids of the 15J type" known' as the Master Car-Builders type 'thelid-is` hinged above; the seat and closes downthereupon. The spring for holding "the lid closed is carried by the -lid and "rests upon aprojectionfrom the 'box substantially inlinetwith the hinge of thelid. This causesthe'spring totend to force the side-of thelid nearestV the hinge away vfrom its seat,

and consequently leaves? an opening between the lid-aridthefseatr` through which dust en- 2 5 ters and as the hinge becomes worn the openingbetween the lid and its seat increases.V The seat -on which the lid rests is rough, not being machined at allLfN-,f lConsequentlythe lid, even` when the boxes aref new, does-not rest on the 30 `errtii'elyclosed, 'Furthermore, my deviceop-v er `a tes to'drawthe lid more firmly down upon l 3 5 its seat than has-heretofore been possible;

- I By Inyinvention I add to any ordinary vjournal-box ld`-such, for instance, as the Master Car-Builderslid-adevice whereby the joint between the lid and its seat is packed,and thus far as the operation of my device is concerned not, as my devicewill pack the j oint and render it tight in any event. f l adapted ,to be added to lidsVv which are in use, it being entirely unnecessary to reconstruct the lid, as my invention is in the nature of an addition thereto and can be readily applied.

Bynny invention this openingis .s owing the lid open. ajournal-box closed with the lid plate which'carries the packing, showingfthei rendered dust-tight, it being immaterial` as 'U'Master Car-Builders lids without changegnI preferivwhen constructing lids which are to have luy-invention applied to makeY the spring :somewhat wider, andconsequently the opening in the lid'through which the spring passes 55 .will have to be made somewhat wider to accommodate the spring. The particular construction of `the lid, however, is entirely im- 4 material to the scope of my invention. Furthermore, my invention is adapted to assist inkeeping'the lid closedland prevent the jar from moving the lid ,on its seat, and consequently keepsthe hinge of thelid from Wearing, as it does at present. By the use of myinvention the only wear on the'hingeis 65 due to the opening and closing of the box. In the drawings forming a part of this ap'-` plication I have shown my yinvention as applied to'a box and lid of the Master Car-.Build ers type; I desire to have it understood that vwhile my invention vis particularly .adapted Y f Qfilse in connection with this type of boxand lid it mayv be used with equal advantage on any other form of boxl and lid that' may be found 75 l "Referringto tthe' drawings, wherein the 8o 1xl'and lid of the Master Car-Buildersftype ith fnyinvention applied thereto,showingthe" d'clsed. Fig. 2 is a view similafr Fig. l,

showing how the packing' is forced into 'the corner;

I designatesa journal-boxQ, thejournal; F 3,-the brass; 4, the seat around the opening `95 in the journal-box; 5, the projecting lug from, the. top of the journal `to which the-lid is l hinged; 6, the'pin running through thepro` jecting lug and forming the hinge .for the lid 7 'Ihe projecting lug 5- has the usualv cam- 100 surface on it, and the lid 7 carries a spring 8, adapted to coact Withthe cam-surface of the lug 5 to hold the lid open or closed. The box and lid are of any usual or desired construction and for the sake of illustration merely are shown as of the Master Car-Builders type. They, however, form no partof my invention and will not be further described.

In yaboutthe center of the lid 7 I cut a slot 9, through which passes the part 10, having a T-head. 11 is acam-lever which is pivoted to the part 10 by the pivot -12. The lever is shown straddling the part 10 and having a cam-surface on each side thereof.,v4 Preferably I cause the cam to have a spring action. When the portion of the cam having the maximum throw is in its operative position against the lid, I cut away the cam-lever, beginning with a part of the cam-face intermediate the maximum and minimum throw portions, back into the cam-lever, so that I form a springar`m113, which carries on its end the portion 14, which gives the maximum throw. The spring-armwhich carries the cam portion 14 is provided for the purpose of firmly holding` the packing in position and also to accommodate any irregularities in the casting of the box at the portion where the packing vcomes in contact with the same or any differences due to wear. It will thus be seen that when the cam-lever is turnedjso the portion 14 is buckled or dished, s o that it has the gen-y eral formwhen in its normal position that is best shown in Fig. 2. The plate 18 is cut and stamped into the dished or buckled form, (best shown in Fig. 4,) whereby a central depressed portion 19 is formed, with the arms 2O extending to the corners of the rectangle and theV triangular portions 21 between the arms 20. Around the edge the portions 2O and 21 are turned iup I.to .form a flange 22, and to this flange is secured a stripV of rawhide or similar vmaterial 23, which forms a packing-ring, the 55y packing material being secured in position by the w1res 21 or other securing means. Preferably and as shown this packing extends around the corner formed by the turning up' of the llange 22. A ,Y

In applying my invention to a box-lid the opening 9 is rst cut in the center of the lid., The portion 10 is then passed through the openingwith the plates 17 and 18 secured to the T-head thereof inthe manner described, and the camrlever is then fastened to the portion 10 by means of the pivot 12. When now the lid is open and the low portion of the cam of the cam-lever is against the face of the lid, the packing-ring on the flanged edge of the plate 18 will rest against the inner surface of the lid, due to the form of the plate. The flanged edges of the portions 20 will extend slightly beyond the flanged portions of the parts 21, due to the fact that the portions 20 are longer than the portions 21, and both are bent down with the edges of the flange in the same plane, the plate being dished to produce this contour. The plate 17 is less dished than the plate 18, so that its outer edge stands some distance away from the packing-ring. Because of the fact that the plate 18 is dished its dimensions, when in an open position measured to the outside of the packing, are less than the dimensions of the seat. The dishing of the plate causes the packing when the cam-lever is thrown up to draw away from the sides of the box, whereby the lid is free to be opened. When now the box is closed, the lever 11 is swung over until the spring portion 14 of the cam rests against the lid. This causes thc portion 10 to lnove through the box and pull the center portions of the plates 17 and 18 toward the lid. This causes the plate 18 to iirst flatten out, because the flange edge is normally in contact with the under side of the lid until the packing-ring makes contact with the inner face of the seat. The spring-arm 13, carrying the cam portion 14, will hold the packing-ring into the corner between the lid and the inner edge of the seat, thus tightly closing the crack between the lid and the seat. The plate 17 has such a dish that it will make contact with the packing-ring before the outer edge of the packing-ring comes into contact with the edge of the seat, and consequently will add its strength to aid in holding the packing'- ring in position. Preferably the plate 17 is solid-that is, has no slots cut in it--as is the casewith the plate 18, so as to prevent any dirt which might work in through the opening in the lid from getting into the box. It is of course to be understood that the spring of the arm 13 should preferably be slightly greater than the spring of the plates 17 and 18 combined. It will be noticed that the packing when the parts are in their normal position is forced against the sides of the '.opening in the box just below the seat and by the tensions of the springs are held iirmly in position. The cam portion 14, bearing on the face of the lid, will consequently hold the lid firmly to its 'seat and prevent wear of the parts due to the' jarring when the box is in service. y

The construction above described is the preferred form of my invention. Myinvention,

however, embraces, broadly, the idea of foreing a packing into the angle formed between the sides and lid of a box, no matter what the particular mechanical construction may be lOO IIO

. 'ferme` r for effecting thisl result. invention alsoA includes all forms of construction wherein the packing is' forced against the inner sides standard types of journal-boxes Vnow in use and-iny no way changes the construction of theseflids. Consequently should the lid of a journal-boxv which was equipped with my'inv vention become lost or broken ka new Master Car-Builderslid or one of other design could be put on even though the new lid was not equipped with my invention, and afterward by merely cutting a hole in the center of the new lid it `could be provided with my device.r

While I have described what I believe to be the preferred form of my invention and the best manner of applying the same, I desire to have it understood that I am not to be" limited to the yparticular means or the particular combination of parts which I have shown and described merely of illustrating my invention.

-Many changes may be madein the construc` tion, form, arrangement,"and combination of parts which carry out my invention without 'departing therefrom, and I desire to have` it f understood that ymy invention covers all such f changes and substitutions.
